摘　　要：涝渍是中国长江、黄河流域棉区棉花产量、品质提高的重要限制因子。棉花常具有复杂的耐涝机制,其中,转录因子在其响应涝渍胁迫中发挥着重要作用。本研究从形态结构、生理生化、基因表达等方面综述了近几年国内外有关棉花涝渍胁迫的研究进展,探讨了胁迫条件下棉花的形态及生理适应性,信号转导过程,重点分析了b ZIP、AP2/EREBP,NAC、WRKY、MYB、b HLH等几大家族转录因子的结构、分类及生物学功能,并对其响应非生物胁迫的复杂调控机制进行了论述,以期为发掘棉花耐涝基因,利用分子手段培育棉花耐涝新品种提供思路。In the Yangtze and Yellow River Valleys of China, waterlogging is one of the most important factorsthat restrict the enhancement of yield and quality of cotton. Generally, cotton has a complex resistancemechanism responding to waterlogging, in which transcription factors（TFs） play an important role. Wesummarized the research progress of waterlogging stress of cotton from morphology and structure, physiologyand biochemistry, gene expression and so on. We discussed the morphological and physiological adaptability,and the signal transduction process under waterlogging stress, especially expounded the structure,classification and biological function of b ZIP, AP2/EREBP, NAC, WRKY, MYB, b HLH and other majortranscription factors, also discussed the complex regulation mechanism of cotton responding to abiotic stress. Itis expected that the study could provide new ideas for exploring the genes of waterlogging tolerance andcultivating new waterlogging-resistant varieties of cotton by molecular technique.
